Add NVP advanced service check before deleting a router

Since NVP advanced services(LB/FW/VPN) are all routed inserted,
it is necessary to check service in use before deleting a router.
    *If there is one service inserted into the router, it would raise
RouterInUseByXXService error when deleting the router.

fix openvswitch requirement check

With VXLAN enabled on openvswitch, neutron checks
module version of the openvswitch kernel module.
If the pattern to extract the version matches twice

This patch ensures, that only the version is checked
against the pattern.
